7. "Scream Queens" (Fox)

While its first season was campy and fun, the latest season of "Scream Queens" feels like a big disaster. Even bringing on heartthrobs John Stamos and Taylor Lautner hasn't kept this show from bleeding out. Its ratings have fallen by nearly 45% over last year's numbers. With its star-studded cast and elaborate sets, the cost of the show at these ratings appears unjustifiable.

But fans may have a lifeline. The fact that Ryan Murphy ("Glee," "American Horror Story") is an executive producer could keep it from cancellation, as Fox may want to preserve that relationship.
